PATCH: _git: fix git-describe completion

[Valentin Haenel <valentin.haenel@xxxxxx>]

The completion for git-describe  misbehaves and outputs an error message
when trying to complete long options.

When typing:

 zsh» git describe --[TAB]

I get:

 zsh» git describe --_git-describe:3: no such file or directory:
 --all[use any ref found in "$GIT_DIR/refs/"]
 dirty=
